EXPLANATORY NOTE

This Post-Effective Amendment No. 1 to each of the following Registration Statements on FormS-8 (collectively, the “Prior Registration Statements”) is being filed by CenterState Bank Corporation (the “Registrant” or “CenterState”) to terminate all offerings under the Prior Registration Statements and to deregister any and all shares of CenterState common stock, par value $0.01 per share (the “Shares”), together with any and all plan interests and other securities registered but unsold as of the date hereof thereunder (note that the share numbers listed below do not take into account any applicable corporate actions, such as stock splits, that may have been taken in the interim):

On January 25, 2020, the Registrant entered into an Agreement and Plan of Merger (the “Merger Agreement”) with South State Corporation (“South State”), pursuant to which, on June 7, 2020, the Registrant merged with and into South State, with South State continuing as the surviving corporation (the “Merger”).

In connection with the Merger, the Registrant has terminated all offerings of the Registrant’s securities pursuant to the Prior Registration Statements. Accordingly, pursuant to the undertakings made by the Registrant in the Prior Registration Statements to remove from registration, by means of a post-effective amendment, any of the securities that remain unsold at the termination of the offerings, this Post-Effective Amendment No. 1 hereby removes from registration all of such securities registered under the Prior Registration Statements that remain unsold as of the date of this Post-Effective Amendment No. 1.
